74LVT244AD-Q100J

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74LVT244AD-Q100J is a high-performance BiCMOS octal buffer and line driver designed for VCC operation at 3.3 V. It features two output enables (1OE, 2OE), each controlling four of the 3-state outputs. Qualified to AEC-Q100 Grade 3, it operates from -40 °C to +85 °C with a supply voltage range of 2.7 V to 3.6 V. The device provides an output capability of +64 mA and -32 mA, with overvoltage tolerant inputs up to 5.5 V. It includes IOFF circuitry for partial power-down mode and bus hold data inputs.

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific package variant against the ordering information table. The AD suffix indicates the SO20 plastic small outline package (SOT163-1). Confirm that the required temperature range matches the specified -40 °C to +85 °C operating conditions. Ensure the design accounts for the 3.3 V nominal supply voltage requirements and the 5.5 V input tolerance limits.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when an octal buffer with 3-state outputs is required for automotive applications. It is suitable for driving bus lines and providing direct interface with TTL levels. The device offers high-speed BiCMOS performance and robust latch-up protection exceeding 500 mA per JESD 78 Class II Level B. Consider the SO20 package dimensions if space constraints align with the SOT163-1 outline.
